One-way impulse type wave power generation device

Abstract

The invention discloses a one-way impulse type wave power generation device which comprises a water absorbing cabin, an air cabin, a flotation tank, an inlet elbow, an outlet straight pipe, a first flange plate, an installation pipe, a one-way impulse type air turbine and a power generator. The air cabin and the water absorbing cabin are jointed through a bolt and are separated through a rotatablealuminum alloy cover plate; a fixing block and a first fixing ring are arranged in the air cabin; the aluminum alloy cover plate is provided with a movable rod arranged in the first fixing ring in apenetrating way and rotating around the first fixing ring; a first end of the inlet elbow is arranged in the water absorbing cabin under the aluminum alloy cover plate; a second end of the inlet elbowis arranged on the upper part of the flotation tank and is provided with a second fixing ring; a rubber sheet capable of clinging to or loosening the second fixing ring is arranged in the second endof the inlet elbow; and the outlet straight pipe is arranged on the upper part of the air cabin and is connected with the installation pipe and the one-way impulse type air turbine through the first flange plate. According to the one-way impulse type wave power generation device provided by the invention, high-efficient conversion from wave energy to air kinetic energy to electric energy is realized, and the energy conversion efficiency is high.

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a one-way impulsive wave energy generating device. Background technique [0002] There are abundant wave energy reserves in the world, and the potential for development and utilization is huge. With the depletion of fossil fuels and people's gradual attention to renewable green energy, the development and utilization of wave energy has set off a wave of upsurge worldwide. Various wave energy power generation devices emerge in endlessly, but these devices are facing The power generation efficiency is low, the cost is high, and it is easy to be damaged under extreme sea conditions. [0003] As far as the current technological development is concerned, wave energy application technologies are mainly divided into fixed and floating. The fixed type is mainly combined with coastal breakwaters. Although it has engineering convenience, its application range is limited and cannot be pr...

AI Technical Summary

Problems solved by technology

The impulsive turbine with bidirectional fixed guide vanes has poor air flow and low energy conversion efficiency because of the obstruction of the downstream guide vanes when it is working; Improvement, but because of the complex production, it needs to face thousands of reciprocating movements per day under actual sea conditions, so it is easy to be damaged, and the engineering reliability is low, which is not conducive to large-scale commercial application

The unidirectional fixed guide vane impulsive turbine has simple structure, high reliability, and relatively high energy conversion rate, but because it only works in one direction, and the unidirectional air inlet is installed Near the level, this makes the energy absorption rate of the overall device low, and the air turbine operation status is unstable and other defects
